*How #SriLanka got ruined*

Lankans voted for #Rajapakshas knowing very well what they did in the past, including corruption, selling out national assets to #China, #dynastic politics and all.

They still voted for them because Rajapakshas promised things they could not refuse.
1. Their #GST, called VAT Tax, on all products was reduced to 8%, thus making everything cheaper in one stroke. (It also killed the govt revenue). People loved things getting cheaper.
2. The minimum #incometax threshold was changed from 5 Lakhs per annum to 30 Lakhs! Very few earned more than 30L!
A very large part of the population became #tax exempt. This was very popular among the salaried class.

Much thanks to @PuntlandPirates work, notes & reflections
- Iranian Gillnetters (indiscriminate way of capturing marine animals-illegal) licensed by officials-Evidence
- Forced labor
- NEFCO tried to sell #Somalia fish privately, facilitates IUU fishing
globalinitiative.net/wp-content/upl…
Global Fishing Watch & #Somalia Gov both reported more than 100 Iranian vessels in Somali waters in 2019-2020

#Puntland issued, lacks legal powers, 52 licenses in less than 60 days to trawlers, illegal in Puntland & Somalia, per doc obtained by @GI-TOC $10k-15k each license
Assuming continuity of the licence fees per year, #Puntland would get $3M-$5M per year.

This money is collected by agents, there are few of them, 5.

One of them is Saddam Ismail, an agent for 8/52 vessels.

He is linked to arms smuggling: delivering arms & picking up fish

Models project that #ocean #phytoplankton will become increasingly starved of #nitrogen as #climatechange progresses.

If realised, this has implications for #fisheries.

But how can we monitor this change in the real ocean?

Nitrogen isotopes!
rdcu.be/cAlW2
What are nitrogen (N) isotopes?

There is a heavy isotope (15-N) and a light isotope (14-N).

Some processes prefer to use 14-N more than 15-N. When phytoplankton use nitrogen, they prefer 14-N.

This increases the ratio of 15-N to 14-N in seawater.
But when N is scarce, phytoplankton have less preference.

Like if there was only one kind of pizza at a party, you don't have the option of being picky (you have to have the pineapple).

In this case, phytoplankton no longer increase the ratio of 15-N to 14-N in seawater.

Our new @BlueFoodFutures paper is now out in @nature. We compare the environmental performance of #bluefoods to prioritize sustainable blue food production and consumption 🧵(1/10)
@AmericanU @AUResearch @sthlmresilience @oceansolutions @eatforum @DalhousieU A market counter with a range of prepared fish and shellfish
Did you know food systems emit 1/3 of all greenhouse gases, occupy 1/2 of ice-free land & are responsible for 3/4 of freshwater use and eutrophication?

Yet, many studies aiming to reduce these pressures largely overlooked blue foods, so we dove into them here (2/10)
We used data from studies covering >2,500 #fisheries & #aquaculture farms to estimate the #greenhousegas, nitrogen & phosphorus emissions, and freshwater & land use to produce standardized estimates for 23 species groups, representing >70% of blue food production 🐟🦐🦪 (3/10)

(1) The 4th stage of the Program by the Min of #Fisheries to build #ArtificialReefs and #FishSpawning habitats with old busses and concrete structures is been successfully conducted in the seas off the #Jaffna peninsula. Earlier stages were conducted in Trinco, Galle and Matara.
(2) The protest by the #TamilNadu #Fishermen against the program stating it as an irresponsible move has been rejected by the #GOSL and will be continued. Similar programs are conducted globally, it has been recommended by the #MarineResearch Institute in SL, #NARA as well.
(3) While it will boost Fish Spawning, #Marine Habitats and #environment damaged over the years by human factors and #illegal fishing methods such as #BottomLineTrawling, it will also act as an shield against bottom line trawling conducted illegally by the #Indian Fishermen.

The blackmailing #Morocco uses against the #EU& #Spain,and the use of two sensitive topics (#migration & #terrorism) has not started with what happened in #Ceuta. It has been the case along the #EU-#Morocco relations’ history. A quick flashback:
1:used to push #EU to accept #Morocco’s claims to join the #EU in the 90s after being lonely/unwanted in its natural continent,the #AU(b/c of its illegal military #occupation of the neighbouring #WesternSahara)->the #EU submitted but proposed an association agreement instead
2:migration used as key element during negotiations of the 2000 #Association_Agreement to maximise the funds provided to #Morocco by the #EU under the agreement and to get what the #EU calls “Advanced status” under the #ENP (European Neighbouring Policy) with related advantages

Primary land for #agriculture #forestry and #fisheries is front page news and may be at the cusp of a generational bull run. Yet, the market hasn’t really factored this in. 🤷

What are some ways we can play this trend?

Let’s take a deep dive. 👇
2. Classical economists like Adam Smith and David Ricardo modelled the economy with four factors of production: Labour, Capital, Entrepreneurship (or ‘technology’).. and land.

Tech and capital used to be the most scarce, but do you think that's the case now?
3. Recently megatrend analysts have been pointing at increasing food and fiber needs, increasing population, increasing wealth, and decreasing land availability all contributing to relative scarcity of good quality primary land.

Here’s the EU projecting declining land..

[1] Reports indicate that the #Venezuelan Floating Storage/Production Vessel, FSO #nabarima, currently located in the #gulfofparia, has approximately 1.2 million barrels of crude oil onboard & the vessel is in distress.

Why is this of concern to #TrinidadandTobago?
[2] The #gulfofparia is a semi-enclosed body of water located between #Trinidad and #Venezuela. The #marine #environment is a very dynamic system. Any oil that is spilled in the #gulfofparia will likely be transported by the currents and reach the shores of both countries.
[3] Presently, the #gulfofparia supports important #fisheries 🐟🦐 Many #fisherfolk in #Trinidad harvest #fish and #shellfish from the #gulfofparia🛥️ The livelihood of these #fisherfolk are dependent on a healthy marine environment.

Yesterday we released a NEW report #WhatWouldNoDealMean.

And, you've guessed it, this report is the subject of today's #ThursdayThread. 🧵

ukandeu.ac.uk/wp-content/upl…
.@BorisJohnson has said that no deal with the EU would be a “good outcome” for the UK.

This report highlights what it would mean in terms of trade, fisheries, connectivity, the impact on citizens, Northern Ireland, economics, security, foreign policy, politics and more.
On #trade, the two sides would revert to #WTO rules.

We’re talking tariffs, customs checks, and regulatory checks. In other words, increased hassle, increased time and increased costs for businesses trading with the EU.

@CSBarnard24 explains.

1. #WSTC6 #FishSesh Purse seine fishing is an emerging arena for seabird #bycatch. However, these are also impacting seabirds with edible #fish oil. #Soaked individuals are disrupted in waterproofing, thermal isolation, flight, and prone to #death. How does this happen? Image
2. #WSTC6 #FishSesh #Chile #shearwaters #albatrosses #gulls are affected by fish oil from the direct discharge of #wastewaters or individuals #trapped in the purse seine gear (mean N°ind./set 8.41-12.90 CI 95%, with 96.87% of all trapped soaked) Image
3. #WSTC6 #FishSesh Feathers showed disruption of micro-structures (barbules) under responding at low oil concentrations (5%). Onboard, soaked seabirds remain under this status after 24h of oil exposure when trapped in fishing gear Image

NEW: The UK publishes its approach to negotiating the future #UK - #EU relationship gov.uk/government/pub… UK already saying that it wants a "Canada", "Korea" or "Japan" style relationship and wants to be seen as a "sovereign equal". None of this likely to fly anywhere...
Here is the document itself with some key bits highlighted (thread) assets.publishing.service.gov.uk/government/upl…
Point 5: "relationship between sovereign equals" is - although UK Gov entitled to say this - delusional. #UK much smaller than #EU and more exposed to EU economically than vice-versa. Sovereignty argument coming through strongly here.
